• Audio may also be transmitted along with video when using HDMI extenders.
  • DisplayPort if less than 10ft away, will also carry audio and video, but DP cannot be extended.
  • If you do not require audio, you may also extend over DVI to extend video only.
  • VEM's are connected over 1 or 2 x CAT6 network cables for each VEM depending on the type of connection used.
  • Customer must provide and run CAT6 cables to each VEM.

What you will need

7 x TV's or monitors to display your content (content display).
Short video cables to connect from the Video Extension receiver module (if used) to your TV or monitor. These short cables are normally provided with your monitors or TV's. If you need to extend video farther than 10' away, choose a Video Extension option during checkout.


Q: What do you mean when you say "content display"? 
A: In the digital signage world, a content display refers to the TV or monitor that you will be using to broadcast your information to. For example, a looping PowerPoint presentation, message board, video, menu, pictures, spreadsheet etc. This is called your "Content Display".

Q: My TV/monitor are LESS than 10ft away from the system. Do I need the video extension options? 
A: No. If your content TV or monitor is within 10ft of the system, you will connect directly to the video card and would not need the extension options. We will include 10ft video extension cables (DVI, DisplayPort) at no charge with the system. Just let us know what type of ports you have on your TV or monitor so we can give you the correct cables. You may let us know this in the comments box during checkout.

Also, if you are less than 10ft away you may use ALL of the video ports on the video card for content displays forgoing the control monitor. You would need a control monitor if more than 10ft away because you would not be able to see what is on the screens any farther away than that.

Q: What is a "control monitor"? 
A: A control monitor is a regular monitor, included with the system and connected on video port #1. It is used to manage the content displays at a remote distance. You would need a control monitor if more than 10ft away because you would not be able to see what is on the screens any farther away than that. For example, let's say your content TV is 100ft away from the system. You will need a way to view what is being shown on that TV 100ft away. That is where the control monitor and Video Extension Modules come in (see below).

Q: If my content display is at a distance, how will I see what is on the screen? 
A: We include a software utility with the system which allows you to "pull" the content back to the control monitor (in the back office let's say), make your changes then "push" it back out to the distant display.

Q: How is the video extended out to the remote content display? 
A: Using our CAT6 Video Extension Modules (VEM), more details above. These are available as options during checkout if needed.

Q: What type of video can I extend with this model? 
A: DVI (up to 160') or HDMI (up to 300').

Q: Can I extend audio as well as video? 
A: Yes, just add our HDMI version of the video extenders to your order during checkout (160ft or 300ft options). If you are NOT extending you can also transmit audio and video over DiplayPort cables under 10 ft.

Q: Are the VEM's difficult to install? 
A: No. Just run 1 or 2 (depending on connection and distance) CAT6 network cable(s) from the DS-Z system out to each of your remote content displays. Connect a transmitter VEM on the system side, and a receiver VEM on the content display end. You will need your own CAT6 cable(s) which can be purchased at any Home Depot or similar store.

Q: Can I use CAT5e instead of CAT6?
A: To get the maximum distance out of the VEM's, CAT6 is required. It is possible to use CAT5e however it will shorten the distance of video extension up to 50% on 1080p. Using CAT6 is highly recommended.

Q: I plan on extending video using your VEM option. Are the short video cables included to connect my TV/monitors to the VEM's? 
A: No, but these short cables (usually about 6ft) come standard with your TV's or monitors. If not they are available at any Best Buy type store.

Q: I do NOT plan on extending video I will connect my TV/monitors directly to the video cards. Will you provide these cables?
A: Yes. If you are NOT extending you will connect your content displays directly to the video cards. We will include either DVI or DisplayPort cables with the system. These cables are about 10ft long and you will get one cable for each port. For example if you have a 7 display system, we will provide 7 x 10ft video cables. Again this is only if you do NOT require video extension beyond 10ft, and you are not using video extenders.

Q: Can I use this system for a message board? 
A: Yes. This system makes a very effective and versatile message board. Schools, universities, libraries, transportation etc are all examples of who use our systems.

Q: Can I use this system for advertising or have a scrolling slide show? 
A: Yes. Microsoft PowerPoint is the easiest way to create your 'content' and that is included and preinstalled for you. Just create your content in PowerPoint and you are ready to go

In the example shown left, our HDMI Video Extension Modules can be used to transmit video as well as audio up to 300' over CAT 6 network cabling.

A small VEM Transmitter module connects to the video source of the DS system on one side of the module, and on the other side outputs to CAT 6.

The matching VEM Receiver module located at the content display on the other end receives the CAT6 input, then outputs to the video source on the content display, in this case HDMI. This option is available during check out.

Video Connections

There are two options to connect to this system based on how far away your content display will be from the system.

If LESS THAN 10ft away, you do not need to use the video extension option. You will connect the video cable directly from the video card ports (DisplayPort, HDMI or DVI), straight to the port on your content display. In this case, we will provide the appropriate 10ft video cables (DisplayPort, or DVI) and adapters with the system based on your selection at checkout. We do not sell HDMI cables but you can pick those up at any Best Buy or office store. No support for VGA on this model.

If MORE THAN 10ft away, you will need to use our Video Extension Modules (see below) to extend the video up to 300' away from the system. These options are also available during checkout.

Extending Beyond 10ft

Video Extension Modules (VEM's): Extend video at a distance of up to 300' using our optional video extension modules (DVI or HDMI). DisplayPort cannot be extended.
